JERUSALEM -- Israel's prime minister has defended the actions of Israel's military in the recent war in the Gaza Strip, saying the heavy civilian casualties were caused by Hamas.
Speaking to international journalists, Benjamin Netanyahu said Israel's intense bombardment of Gaza was a necessary response to Hamas attacks.
"It was justified. It was proportionate," he said.
Nearly 1,900 Palestinians were killed in the fighting, most of them civilians, according to Palestinian medics. Israel says some 900 Palestinian militants were among the dead.
Netanyahu said he regretted "every" civilian death, but that Hamas was responsible because it carried out attacks from civilian areas.
More Americans blame Hamas than Israel for the recent fighting, according to a new CBS News poll. Thirty-four percent think Hamas is most to blame, while just 6 percent lay most of the blame on Israel. However, nearly half - 47 percent - think both sides are equally to blame.
Meanwhile, indirect Israel-Palestinian negotiations over extending a cease-fire in the Gaza Strip and ending a blockade of the territory got underway in Cairo on Wednesday, with positions from both sides maximalist and much jockeying expected ahead.
CBS News correspondent Charlie D'Agata reported from Tel Aviv on Wednesday that despite the longest lull in fighting since the current crisis began, the cease-fire felt more like a standoff, and the prospect of a return to war wasn't far away; Israeli tanks were still positioned right on the Gaza border.
Whether the calm lasts, said D'Agata, was entirely dependent on the success of the talks in Cairo. Israel wants the Islamic militant Hamas to disarm, or at least ensure it cannot re-arm, before considering the group's demand that the territory's borders be opened. Israel and Egypt imposed a closure after the Hamas takeover of Gaza in 2007, although Egypt allows individuals to cross intermittently.
"The two sides have reviewed what they consider as issues of concern," Egyptian Foreign Minister Sameh Shukri said at a news conference, describing the matter as "complicated and not easy."
Egyptian mediators have been shuttling between the delegations, and an Egyptian airport official said the Israeli delegation was back in Cairo Wednesday evening after flying out earlier in the day. He spoke on condition of anonymity because he was not authorized to brief reporters.
The Palestinian delegation is composed of negotiators from all major factions, including Hamas, and is meeting with Egypt's intelligence chief for briefings on Israel's demands.
"The most important thing to us is removing the blockade and start reconstructing Gaza," said Bassam Salhi, a Palestinian delegate. "There can be no deal without that."
He said the cease-fire, set to expire at 8 a.m. Friday (0500 GMT), would likely be extended if more time for talks is needed. Shukri said that he hopes it would be extended.
The negotiations are still in the early stages, but the outlines of a possible solution have emerged, including internationally funded reconstruction of Gaza overseen by a Palestinian unity government led by Palestinian President Mahmoud Abbas. The Western-backed Abbas lost control of Gaza in the Hamas takeover of 2007.
In a step toward reconstruction, Norway is organizing a donor conference, tentatively set for the beginning of September.
Regarding easing the blockade, a statement by Egyptian intelligence indicated it would not agree to major changes at the Rafah crossing between Egypt and Gaza, and the onus of lifting the border closure would fall on Israel.
Egypt considers Gaza occupied by Israel and the country responsible for Gaza's other heavily restricted border crossings that lead into the Jewish State. Cairo also refuses to open its border fully as long as Hamas, not the Palestinian authority led by Abbas, controls the Gaza side of the terminal.
"Israel is the one that sealed all the crossings from the Israeli side and it doesn't allow commodities and goods or individuals to cross, aiming at besieging the strip and throw the whole responsibility on Egypt," the statement said.
The statement also took aim at Hamas, saying it was not permitting its own wounded population to cross into Egypt.
"The Palestinian party continued to put obstacles in front of the families, allowing only its foreign members to cross while barring its Palestinian members under the pretext that Egypt is barring them," it said.
Rafah is closed to commercial traffic and allows only individuals to cross, but Egypt has sharply restricted travel rights of Gaza residents over the past year and waiting lists have grown.
Speaking at his news conference, held with his Venezuelan counterpart, Shukri said talks are giving priority to the Israeli-controlled crossings and how to operate them to "meet demands of the Palestinian people."
The cease-fire, in its second day, is the longest lull in a war that has killed nearly 1,900 Palestinians - 75 percent of them civilians according to the United Nations. Israel has lost 67 people, including three civilians.
The current round of confrontations began with the June 12 abduction-killing of three Israeli teens in the West Bank, which Israel blamed on Hamas before launching a roundup of hundreds of its activists, a move followed by barrages of Gaza rocket fire on Israel.
Israel launched airstrikes on July 8 it said were aimed at stopping the rocket fire before expanding the operation on July 17 by sending in ground forces to destroy a network of tunnels used to stage attacks.
On Wednesday, Israel's Justice Ministry said it had arrested Hussam al-Qawasmi, the suspected mastermind behind the killing of the Israeli teens, in July.
He allegedly led a three-man cell, all of whom were affiliated with Hamas. The militant group has not claimed any connection to the teens' abduction and killings.
In Gaza, people took advantage on Wednesday of the calm to return to their devastated homes and inspect the damage.
People trickled back to their homes making their way over buckled roads, through dangling power lines and overturned trees to inspect their neighborhoods. Along the way, rows of flattened buildings alternated with moderately damaged structures - and rare buildings with no damage.
Cars and donkey carts loaded with household goods and mattresses filled the streets and queues formed at banks as people waited to withdraw cash from ATMs.
Crews from utility companies worked frantically to repair downed electricity and telephone lines. Gaza's only power plant was shut down after it was badly damaged by an Israeli attack and repairs are expected to take months.
The densely populated strip now only has 2-3 hours of electricity a day which trickles in from Egypt and Israel.
